Weightlifting is a highly technical sport. Traditional approaches of analyzing lifts and training often rely on the subjective assessment of the coach (and athlete), which can limit the precision of feedback. In this work, these traditional methods are complemented by sport-specific parameters, such as peak vertical barbell velocity and power output. The use of a measurement system is essential for improving the understanding of movement, optimizing technique and learning, enhancing performance and injury prevention.
This master’s thesis investigates advanced methods and tools for monitoring athlete’s readiness and conducting biomechanical analysis of Olympic lifts. We will develop an application designed to capture and track key performance parameters specific to weightlifting training. Using time-synchronized devices including a sensor-based system, a professional optical tracking system, and force plates, we analyzed weightlifting technique through graphs of vertical ground reaction force, vertical barbell velocity and displacement. We are also going to do an analisys of weightlifting technique by measuring barbell trajectory and center of pressure (CoP). In the next phase we will measure daily readiness of an athlete in 10 weeks leading up to the competition and load velocity profile of five weightlifters during the snatch, using a wrist mounted sensor system. Finally, using force plates, we will analyze and compare the power and elastic qualities of 13 athletes.
